I’ve been spending a lot of time lately with Twitter Bootstrap 3 – the new mobile-first version, and Foundation 4. It all started when I decided to check out Twitter Bootstrap. At that time it was still at version 2.3.2, the prior version to the current Twitter Bootstrap 3 RC1. I used it and liked it until I had a need to exert more control over how my site would look on mobile devices. When I ran into that issue, I hightailed it for Foundation 4. What I found blew Bootstrap 2.3.2 out of the water.
Font Awesome by Dave Gandy is “the iconic font” designed for use with Twitter Bootstrap. But guess what? You don’t have to use Twitter Bootstrap. Font Awesome can be used with any site or framework.
Beyond the 249 icons, my favorite thing about Font Awesome is how designer friendly it is. Just install FontAwesome.otf and visit the copy and paste page when designing. You can also contribute your own icons. Although to submit your icon, you’ll need to email Dave at firstname.lastname@example.org so he can approve your icon for submission vs sending a pull request. He’s keeping a very tight reign on quality.
jKit is a new toolkit for jQuery, built by Fredi Bach from Switzerland, that I think has much to offer for those with HTML prototyping needs (the way prototyping is ought to be done I believe). The toolkit contains quite a few widgets, interactions and behaviors that help to enhance the UI while at the same time lowering the programming barrier to entry. Some of the many things that the toolkit allows for includes: a carousel, tooltips, form validation, zooming interactions on images, list cycling for styling, auto scrolling, etc, etc, etc. Anyhow, there is a lot more to it so have a look at the awesome examples and see if you it fits your needs for the next prototype you decide to build.
